Yep: the CC to bug-bison.

Other than that, I am the one who missed an important point: we
compile this file only when needed, and it appears it is not `needed'
on your platform, but it is not the same version as the usual one,
since it does not seem to provide `error_one_per_line'.  That's weird.

Do you have a `man error_at_line' or something?  Could you also look
for `error_at_line' in config.log?  I have this on my machine:

configure:5418: checking for error_at_line
configure:5442: gcc -o conftest -g -O2   conftest.c  >&5
configure:5445: $? = 0
configure:5448: test -s conftest
configure:5451: $? = 0
configure:5461: result: yes
